Abstract
A brake lining comprises a lining support plate, an underlayer material and a friction lining. The brake lining is clamped between a pressure plate and a holding fixture, which forms a hole matrix and inside of which electrodes are accommodated. A power supply is connected to the electrodes. The adjacent electrodes have different polarities. A current flow is produced between adjacent electrodes as a result of the different polarities. The field lines extend in the shape of an arch. An arrangement of this type permits the friction lining to be scorched. For hardening, a potential gradient can also be applied between the electrodes and the support plate. The current then flows and the entire friction lining is permeated. This results in a homogenous heating of the friction lining. The invention enables an efficient hardening of the friction lining. It is also possible to conduct a hardening and scorching simultaneously. The invention also enables the friction lining to be pressed during the heat treatment.
